In the meantime, we are delighted to share with you some further information regarding lung function testing;

Why are lung function tests performed?

There are several reasons for performing these tests, which may include the following:

  • To help make a diagnosis and to quantify the degree of lung damage.
  • To assess the progress of an existing breathing condition by comparing tests with previous results.
  • To see how your breathing condition improves with different treatments.
  • To help assess fitness before surgery.

 What is a lung function test and how do I prepare?

Lung function tests look at how well your lungs work and involve simple procedures/tests to give the medical practitioner accurate information about your lungs and breathing. Prior to the test you may be advised;

  • Not to wear tight clothing for your appointment as this constricts your lungs.
  • Not to smoke for at least 1 hour before your appointment
  • Not to take vigorous exercise, 30 minutes before your appointment
  • Not to have a heavy meal up to 2 hours prior to your appointment
  • Not to consume alcohol for a minimum of 4 hours

What happens during a lung function test?

The lung function test is a painless procedure and usually takes around an hour dependent on the tests performed. It involves a series of breathing tests consisting of breathing and blowing through different tubes connected to special equipment. Routine lung function tests can include spirometry, lung volumes and gas transfer.


Spirometry is a test that shows how well you breathe in and out. The device that is used to make the measurements is called a spirometer. You will be asked to breathe in fully and to blow out as hard and fast as you can into the mouthpiece of the spirometer. You may have to repeat this a number of times.

Lung volumes

Measuring lung volumes (the total size of your lungs) can give more detailed results. This test involves sitting with a clip on your nose to make sure that no air escapes from your nose. You will be asked to breathe into a mouthpiece similar to that of the spirometer. The test is not painful.

Gas transfer

This test measures the amount of oxygen that passes from your lungs into your blood. You will be asked to breathe in a harmless gas through a mouthpiece. Once your lungs are full, you will be asked  to hold your breath for about 10 seconds and then breathe out the gas. The gas will be tested to see how much oxygen comes from your lungs.

What happens after my tests?

We would not expect any side effects during or after these tests. The patient however may feel a little tired, as usually patients are asked to do the breathing exercises a number of times. This is normal and the tiredness will disappear quickly.  The results will be shared with the organisation/clinician that referred you for lung function testing.
